Fabrication and Properties of Zinc Composite Coatings for Mitigation of Corrosion in Coastal and Marine Zone

Abstract

Deterioration of metals and alloys during service due to corrosion and wear phenomena shortens materials life span and structural integrity particularly in aggressive environments such as coastal and marine. This degradation also limits the use of these materials in most industrial applications. Therefore, the improvement of the quality of these materials in order to combat these challenges in industry remains critical. Surface modification techniques are employed to enhance materials properties to enable better performance and to extend their applications in demanding environments. Electrodeposition has been a useful method developed to improve the corrosion and mechanical properties of materials. In the present contribution, ample knowledge about electrodeposition of Zn composite/nanocomposite coatings and their characteristics are reviewed to address coastal and marine degradation of metals and alloys.

Hybrid Zinc Coatings with Improved Corrosion Resistance Based on Chitosan Oligosaccharides

“…The reason for this is the urgent need of cheap and increased protection measures against corrosion destruction [1,2]. This dangerous process is often a result of the interaction of the metals with chloride ions from the surrounding environment [3]. One possible way to reduce the corrosion damages is the usage of low-carbon steels with accessorial protection based on corrosion resistive coatings (metallic, alloy, hybrid etc.)…”

“…This dangerous event is often induced by chloride ions [18]. Their action generally leads to destruction of buildings, bridges, railway facilities, etc.…”

Studying the influence of current density and solution pH on corrosion properties of obtained Zn‐nano SiO2 electroplating layers

“…Studies on composite coatings have pointed out that the corrosion resistance and mechanical properties of these coatings were better than those of traditional metal coatings. [4,5] It is important to optimize the conditions to obtain a composite coating with a good microstructure and particle dispersion because the quality of the composite coating depends on the plating conditions, besides the particle density, concentration and incorporation. [7][8][9] Tuaweri et al [9] studied the influence of current density, plating time, particle concentration, agitation on current efficiency, and precipitation properties of Zn-SiO2 composite coating.…”
